Introduction
In general, stomach pain after diarrhea may be caused by intestinal spasms, dietary irritation, acute gastroenteritis, irritable bowel syndrome, gastric ulcers, or other reasons. Individuals can relieve discomfort according to their specific conditions through dietary adjustments, medication, and other methods. In daily life, attention should be paid to food hygiene, avoiding overeating and irritating foods, and maintaining regular作息 (daily routines) to enhance gastrointestinal resistance.
Generally, stomach pain after diarrhea may be caused by intestinal spasms, dietary irritation, acute gastroenteritis, irritable bowel syndrome (IBS), gastric ulcers, or other reasons. Individuals can alleviate discomfort according to their specific conditions through dietary adjustments, medication, and other measures. A detailed analysis is as follows:
1. Intestinal Spasms: During diarrhea, disordered intestinal motility and excessive contractions can lead to spasms, with pain radiating to the stomach area. Avoid hard-to-digest foods, gently massage the upper abdomen, and drink warm water to soothe the intestines.
2. Dietary Irritation: The gastrointestinal mucosa is fragile during diarrhea; consuming spicy or cold foods can worsen mucosal irritation and cause stomach pain. Adjust the diet promptly to include mild foods such as porridge or well-cooked noodles, and chew slowly to reduce gastrointestinal strain.
3. Acute Gastroenteritis: Pathogen infection causes inflammation in the stomach and intestines. Inflammatory factors stimulate the mucosa, leading to congestion and edema, resulting in stomach pain and diarrhea. Under medical guidance, medications such as norfloxacin capsules, montmorillonite powder, and berberine hydrochloride tablets may be taken. Maintain a light and hygienic diet.
4. Irritable Bowel Syndrome (IBS): Gastrointestinal dysfunction causes heightened intestinal sensitivity after diarrhea, which may affect the stomach and lead to discomfort. Under medical guidance, medications such as pinaverium bromide tablets, bifidobacterium triple viable capsules, or trimebutine maleate tablets may be used. Maintain regular eating habits and avoid emotional fluctuations.
5. Gastric Ulcer: An existing ulcer on the gastric mucosa may be aggravated by increased gastrointestinal motility during diarrhea, causing pain. Under medical supervision, medications such as omeprazole enteric-coated capsules, hydrotalcite chewable tablets, or rabeprazole sodium enteric-coated tablets may be taken. In severe cases, partial gastrectomy may be required.
In daily life, attention should be paid to food hygiene. Avoid overeating, binge eating, and irritating foods, maintain regular作息 (daily routines) to strengthen gastrointestinal resistance. If stomach pain persists or is accompanied by vomiting blood, seek immediate medical attention to identify the underlying cause—do not delay treatment.
